Texas Instruments TI-30X Calculator Cover

thingiverse

This is a cover for the Texas Instruments TI-30X calculator (specifically designed for the TI-30X Plus Mathprint, but I think they are all the same). The cover fits pretty well, but not perfectly - the pins that slot into the calculator protrude a tiny bit too far in my opinion, but you could try filing them down if that is the case with your print. There are four slightly recessed circles on the back with a diameter of 8.5 mm where you can glue rubber feet into place if you want.
